I own a park model trailer and due to its age and size restraints I am hoping to be able to install a auto am/fm radio in place of the broken receiver now in place.
Please, can anyone advise if it is at all possible to install an auto radio to a regular home circuit? Is there a specific type of wiring harness or adaptor available for this type of installation?
Any assistance would be greatly appreciated.

You just need to go to an electronics type store and purchase a simple plug in transformer that will change your 120v line voltage from the recepticle to 12 volts dc for the car radio.

Thanks Mattison,
Is their any other style of connector available for the other wires (except for speaker wires) or can I just wire the 2 power wires together, (red & yellow) and all ground wires together by only using the transformer?
many thanks,
Norm

If I remember correctly there is a place on the back of the invertor/transformer for the + and - wires from the radio. It is just a simple matter of hooking up the dc radio to the back of the transformer which you plug into the regular ac circuit.

Thanks for your help marksr.
I will investigate further at Radio Shack and see what I can come up with,

You can also go to any legit car stereo install place and see what they got going. They will always have a test stand using residential voltage.

Pay attention to the amperage draw. Radios can pull a lot of DC power. You need a power supply that's rated for at least the same amps as the radio's fuse. A too-small wall-wart power supply can wind up heating, failing, or causing a healthy buzz in the radio. This happens all the time in schools, where the music source for the paging system is a car stereo.

The supply should also be regulated and filtered, which means it's going to cost quite a bit more than a $5 RS special.
